Were you using a divided (TS) manifold with the 18cm housing?

I'll be switching to a holset next month. I just picked up a 6 blade HX40. With the 16cm turbine housing. I don't know what way to go with it though. I want to keep my existing header (punishment racing made to clear a 35R) As well as my external waste gate. Should I weld the internal flapper shut and run this housing? Or switch to the BEP t3 .70 ar housing? This is going an a fully built 2.0L with 9:1 compression and HKS 272 cams. As well as all supporting mods. Which way would be best for me?

Guys that provided the info on oiling. thanks.
I already have the line from teh OFH and the fitting on the turbo. I might just do that nitrous restrictor thing though.

Thanks

No, i was using a cheap ebay non-divided manifold that was given to me for free on both holsets. I will be making an adaptor for my JHRacing manifold just to see what the difference is, but that probably wont be untill after i play around with the hx52 a little bit.

Unless you are going to use a twin scroll manifold, id suggest the 16cm housing unless you already have an 18cm housing for it. If my 16cm housing wasnt messed up i would have used that on my setup instead of the 18cm.

Id at least try the 16cm housing first especially if you can weld it yourself. If you like it, then you just saved some money

I don't know if this has been asked or answered. But can I get the 6 blade hx40 wheel for my 8 blade hx40. Would the compressor cover need to be machined? Is this even possible?

Yes, you ca buy the wheel and compressor cover here. Ask Justin (jusmx141) if the hx35 shaft is the same diameter as the hx40. I think they are. If so then that kit will work. You need to buy the cover too because the 6blade and 7blade hx40 compressor wheels hve a 60mm inducer and the 8blade has a 58mm inducer. You may be able to have the cover machined for it, but I don't know if the cost and time tracking down someone who can is worth it or not.

Yes, the compressor cover would need to be machined for it to fit. Most places (diesel shops) will charge $100-$150 to do it.

I just came across an hx40 but it has the 6-blade 56mm inducer. I've searched but I haven't found any info on this particular setup. Is this turbo worth the effort or should I try to find one of the more popular versions? I've maxxed out my td05 20g and I'm looking for an upgrade to get me in the 550hp range. Any info would be greatly appreciated.

6blades are 60mm inducer while 8blades are 58mm i believe. Any pics? It could be a bad measurement by the seller?
You could consider upgrading the turbine wheel on your 20g to td06h for a more power capability as well. The tdo5h turbine cant really match flow with 20g compressor above 24psi or so

I'm thinking you must be looking at the same seller as me, I just bought a 6-blade hx40w, the seller stated it had a 56mm compressor wheel. I wasn't aware that they had a different size 6-blade other than the 60mm wheel.

I'm going to try it. I had Paul (99gst_racer) undelete the second post in the thread. I moved and added some brief highlights for posts for each page. I'm only through page 2 so far. I have to go back and bump the post count 1 to account for this additional post at the start. I might make it like the very first post (linked) so you just click each post link to view it, but it's even more time consuming, so no promises there.

We'll see how it works.

I need to contact Ludachris to see if a post can be added at the start of each of the Holset threads to do the same in the them.

This is true- the first HX40 I ever bought definitely has a 6-blade compressor wheel smaller than 60mm. I couldn't get an actual measurement because all (6) compressor inducers were mangled beyond recognition. It was apparently an oddball- I couldn't find parts for it anywhere going by the stamped number on the cover, and once I finally located a compressor wheel for it the price was double what I thought it should be. This particular turbo had "Volvo" on the compressor tag.

I ended up parting that turbo out, making more from selling the 16cm2 turbine housing alone than I paid for the turbo.

Any idea how long ago the turbo was manufactured?

The comp inducer is definitely 56mm, I measured it myself. It has volvo on the tag also. I did google this turbo and came up with a little bit of info on the cummins forum. The turbo is in excellent shape, that's why I would like to use it. Other than the inducer it looks identical to any other hx40.

Did you measure the turbine wheel at all? Is it the usual hx40 turbine? Any idea of year manufactured?

I wonder if this compressor map is for the 6blade hx40. ????? The 7blade hx35 shows 57lb/min on the map and has a 56mm inducer. Here is the 8blade 58mm standard hx40 compressor wheel with the highest rpm curve missing. I added it based on the 2 other standard 40 maps.

The 16cm^2 housing is definately worth the whole turbo. They are hard to find. And I personally think would give the best compromise for flow and spool with a divided runner. And having a t3 bolt pattern, you have more options. The 16cm^2 turbine housing would be PERFECT for something like the standard 8blade 60lb/min hx40. . . with a divided runner manifold. Only thing that could be better would be the faster spooling pro40 10 blade turbine wheel with the 8blade hx40 in the 19cm^2 t4 turbine housing. Probably the same flow and spool but at a lower backpressure. Custom made holsets make me all warm inside. Would be nice to be able to get these turbos with more options readily available.

So you wouldn't recommend the bep mitsu housing? I'm sort of on a budget with this car and as of right now it's easier for me to buy a bolt-on mitsu housing for $250 than purchase a manifold and o2 housing.

I just bought this turbo, can someone conform for me exactly what the specs of it are. I know its a 6 blade hx40 but I am unsure of the exhaust housing. I am looking to get a ebay manifold to bolt it right up. Any help is greatly appreciated.

^^^The specs are right on the ebay ad.



Gbradly, I didn't recommend any particular housing. I was just saying my above suggestion would be *ultimate* and *ideal* for that compressor size. A divided runner t3 or t4 manifold is VERY expensive. I was talking about those wishing to build a true twinscroll setup. The bolton 8blade hx40 has done a 580whp trap speed at 33psi. It's a hell of a turbo for a bolton.

So I bought a 6 blade 16cm hx40, correct? I am assuming reading all of this that a BEP housing would be a waste of my good 16cm housing and getting a t3 manifold would be a great Idea. My mod list is as listed: 8.3wiesco, eagle rod, eagle crank, 255, 1000cc injectors, 3" exhaust, dsm link, Springs and retianers, stock cams, ss valves Evo316g, 2gmani, tiel38mm, buschur fmic, 1g bov.

I plan on gettin fp2 soon.

I never suggested that the 16cm^2 housing with an open t3 header would be a great idea. It will spool after 4500rpms that's for sure, as the 16cm^2 housing is larger than a .70 a/r BEP t3 housing. It will spool probably 1000 rpms faster and flow VERY well, probably more than you would ever need for a 60lb/min compressor IF you get a divided t3 manifold. You know like those $1200 shearer divided manifolds. You could fab your own like another here has done. But if you want it on easily and on now, the bep bolt on housing is fine. As I said it made VERY good power without too much boost. And spool will be over 20psi by 4100rpms.

I am looking for a better spool and I can't afford the divided manifold so I am going to look into a trade +$$ for someones BEP housing for mine, if anyone is interested. How much does a divided manifold go for anyway?

Wow I'm in my basement for a few days and this thread just explodes. Ok let me clear up a few things I noticed where wrong.

1. You can't add your boost to your base fuel pressure and try to calculate added fuel injected. The reason for the raising rate FPR is that the injector has positive or negative pressure on the pintle of the injector which will definitely effect fuel flow. All that is needed to attain the almost same amount of fuel flow is to change the fuel pressure behind the pintle the same amount as the pressure on the front of the pintle. So 660cc injectors with 44 PSI of base pressure pushing 30 PSI of boost is still pushing the same amount of fuel.

1a. The main reason for running lower than 44 PSI of base fuel pressure is for those people that are running very very large injectors. You do it to effectively make your injectors smaller and try to get an attainable idle. But even at max boost your injectors are still not putting out the correct amount of fuel so they will always be smaller unless you get a 2:1 or 1.5:1 raising rate FPR.

2. Chuck Norris isn't officially running anyones turbo. No one ever has seen under his hood and lived to talk about it.

3. Jack Baurer ?????

I'm not just waiting on an exhaust manifold and Head Gasket to be built. Both happen to be out of stock even at the builder so I have to wait for them to be built.

I also checked out the King Kams next to the BC288's and they are just huge. I have already returned the BC288's but I do have a few sets of stock turbo cams laying around. I'm definitely going to have to take some pics side by side. I'm not expecting much bottom end but top end should just be monstrous.

So if I found this Holset Despieces Modelo HX40W - 3537130 de Holset - Turbos - TurboMaster I know it's a hx40, but how can I figure out if it's a seven blade with the billet wheel or not?
